182 Morris — Nomenclatural Authority for Govionemvs murhachii, 



G. depressum, Yokohama, Japan. Goto, S., 1903; Mark 

 Anniversary Volume, p. 12, pis. II., III.[*]" 



Mayer's reference to Murbach after the type locality for 

 G. murhachii is misleading as implying Murbach 's naming the 

 species, if one notes the value of the other citations in this list; 

 and is Mayer's first use of the binomial with reference to previ- 

 ously published description (Perkins's), in lieu of a description 

 by himself. 



To give the true facts, the reference should be corrected 

 under GonionemMS, as treated by H. B. Bigelow t in his paper 

 on Medusae, page 105, February 1909, as follows: 

 Gonionemus A. Agassi z, 1862. 



Since the [original] description of the [type] species of this 

 genus, Gonionemus vertens, by A. Agassiz (1862, not " 1865 "), 

 six additional species have been described : G. murhachii Perkins 

 (1902, 1903, not " Mayer 1904 "), G. suvaensis Agassiz and 

 Mayer (1899), G. depressum. Goto (1903), G. agassizii Murbach 

 and Shearer (1902, not " 1903 "), G. pelagiciis Bigelow (1904), 

 and G. hornelli Browne (1905). [Bigelow, page 107, cites the 

 last two as synonyms under G. sucaensis.] 



The bibliography given by Bigelow contains 159 titles; but 

 does not include two or three of those given in the discussion 

 above, referring to priority publication of the species in ques- 

 tion . 



The above facts have led to the correction of the authority 

 for the binary name Gonionemus murhachii, and the corrected 

 synonomy is here presented.
